HumiSeal UV50LV UV Curable Acrylate Polyurethane Conformal Coating
HumiSeal is the only supplier specialized in conformal coating manufacture. They have been innovating for over 50 years and creating products that utilize natural occurring resources whenever possible. HumiSeal ta
kes pride in the goal and commitment that within the next 40 years they aim to reduce the release of carbon dioxide by 60%. Fossil fuels are expected to become uncommon in about the same time frame; so, their devotion has become fixated on the practical task of harnessing nature’s resources in the form of wave, tide, wind, photovoltaic, biomass, geothermal and fuel cell technology to attain most of our electrical supplies.
HumiSeal UV50LV is a dual cure acrylate polyurethane, it is one-part, high solids, low viscosity conformal coating. UV50LV has outstanding chemical resistance with moisture resistance and impressive flexibility. This coating equipment has been established at a low viscosity which allows the use with a film coater. After HumiSeal UV50LV is exposed to UV light and its secondary moisture cure, it become a tack free surface. After 7 days of ambient conditions, it will completely cure all unexposed areas of the coating. When HumiSeal UV50LV is cured, it will have a higher flexibility compared to most other UV curable conformal coatings which allows for improved performance in the thermal cycling test. Under UV lighting, HumiSeal UV50LV allows the coating inspections and may be applied by all selective coating equipment. It contains not solvents or VOCs.

HumiSeal UV50LV has a density of about 1.0 to 1.1 g/cm3 and has a room temperature shelf life of about 12 months. This product can be applied both by spray and brush. Conformal coatings can be applied successfully to areas that have been prepared prior to coating as well as assembled with minimal residue, “no clean” assemblage materials. HumiSeal UV50LV has modelled the performance using Arc and Microwave UV curing equipment. To clean up uncured HumiSeal UV50LV, use a non-alcohol-based solvent should be used.
